Biomimetic buildings.
The more technology advances, the more there seems to be a basic human yearning to return to nature. This is reflected in a growing number of designers, architects, and artists who are turning to nature’s example to model uses of new technology. San Francisco architect Charles Lee does just that. Lee is a designer, artist, and researcher with the group Bios Design Collective, a group that works...
متن کاملMoufang Buildings and Twin Buildings
The “Moufang Condition” for spherical buildings was introduced by J. Tits in the appendix of [9], as a tool to give more structure to the classification of spherical buildings of rank at least three (which are automatically “Moufang”). More recently, also the spherical buildings of rank 2 satisfying the Moufang Condition are classified [13]. Hence one could say that, on the geometric level, sph...
متن کاملBiomimetic chemistry
Several cases are described in which the chelate effect contributes to binding and catalysis. In the first examples, dimers made up of linked cyclodextrins show very strong selective substrate binding, and with catalytic groups in the linkers they are effective catalysts of reactions of bound substrates. In later examples, chelate binding of transition states by a base and an acid produce effec...
متن کاملBiomimetic materials
Life is a specific characteristic of our planet. The diversity of life, biodiversity, is one of the most fascinating phenomena. We know some 1.8 million different species, but all extrapolations show that probably 20 million or more species exist: We know less than 10% of the plants, animals and micro-organisms living on the planet Earth. The editors, who are both biologists, are well acquainte...
متن کاملSystolizing Buildings
We introduce a construction turning some Coxeter and Davis realizations of buildings into systolic complexes. Consequently groups acting geometrically on buildings of triangle types distinct from (2, 4, 4), (2, 4, 5), (2, 5, 5), and various rank 4 types are systolic.
